All systems, including Linux, are vulnerable to dumb users opening executable attachments.

You're wrong, of course, because the attachment is not executable under Linux, and will not run, until it's detached and the executable permission is applied by the user. This takes an overt act; simply clicking on the attachment will not do it.

If you ever used Linux, you'd probably know this.

Well, if it's an archive, then the permissions could be preserved within the archive. Still, it would require more effort just to run the attachment as it would require unpacking the archive and I don't think that there are any Linux clients written badly enough to allow someone to unpack an archive and run executables therein in a single step.

Of course, damage would only go so far as the user's permissions.

The latest patches from M$ prevent automatic launching as well. But M$ had to downgrade the feature because of hacker exploits, whereas apparenlty Linux never had it to begin with.
